Benefits of technology

[0008]Certain embodiments of the disclosure provide an augmented reality application that uses perspective projection and a properly configured field of view to display virtual objects with additional realism. For example, using perspective projection, virtual objects that are far way appear smaller than virtual objects that are close by. By overlaying virtual objects of a surface layer (e.g

Problems solved by technology

Orthographically projected virtual objects, however, often result in a virtual visual layout that is inconsistent with the human visual system.
Consequently, a user's resulting visual experience of the virtual world is unnatural, inaccurate, and unintuitive.
Furthermore, the field of view parameters used by many such AR software applications make visual interaction with and the movement and positioning of virtual objects appear unnatural and inaccurate.
Improper field of view parameters also undermine a desired visual relationship between a virtual object and its physical counterpart.
Improper field of view parameters can result in virtual objects being dis

Embodiment Construction

[0019]In the following detailed description, numerous specific details are set forth to provide a full understanding of the present disclosure. It will be apparent, however, to one ordinarily skilled in the art that the embodiments of the present disclosure may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail so as not to obscure the disclosure.

[0020]FIG. 2 is a block diagram 105 illustrating an exemplary client 110 according to certain aspects of the disclosure. The client 110 can be connected to a network 150 via a communications module 118, for example, in order to connect to a server. The communications module 118 is configured to interface with the network 150 to send and receive information, such as data, requests, responses, and commands to other devices on the network. The communications module 118 can be, for example, a modem or Ethernet card. The network 150 can include, for example,...

Abstract

Methods for augmenting a view of a physical environment with computer-generated sensory input are provided. In one aspect, a method includes receiving visual data providing for display an image of a physical three-dimensional environment and orientation data indicating an orientation of a device within the physical environment, and generating a simulated three-dimensional environment. The method also includes providing the image of the physical environment for display within the simulated environment, and providing at least one computer-generated visual object within the simulated environment for overlaying on the displayed image of the physical environment. The computer-generated visual object is displayed using perspective projection. Systems and machine-readable storage media are also provided.

Description

BACKGROUND[0001]1. Field[0002]The present disclosure generally relates to computer data, and more particularly to the use of a computing device to display data.[0003]2. Description of the Related Art[0004]Augmented reality (AR) is commonly described as a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensor input such as sound, video, graphics or global positioning system data. AR software applications are often used on mobile devices to assist users in finding physical objects or locations in the physical world by displaying computer-generated visual objects near the physical objects or locations.[0005]AR software applications that provide a direct view of a physical world environment commonly use orthographic projection (or orthogonal projection) to display computer-generated visual objects. Orthographically projected virtual objects, however, often result in a virtual visual layout that is inconsistent with ...
